Support structure of electroosmotic member, electroosmosis pump, electric power generation apparatus and electronic equipment

Abstract

Disclosed a support structure of an electroosmotic member including: a support structure; an opening formed in the support member in which an electroosmotic member is disposed; and at least one of an elastic piece to separate the opening and the space from each other and to support the electroosmotic member, a cushioning filled in a gap between a wall of the opening and an edge of the electroosmotic member to support the electroosmotic member, and a projection provided on a wall of the opening to support the electroosmotic member, wherein the elastic piece, the cushioning and the projection supports the electroosmotic member which absorbs an impact or a vibration, and when the impact is applied to the support member (housing), an impact load applied to the electroosmotic member can be suppressed and thus, even when the impact is applied, it is possible to prevent the electroosmotic member from being damaged.

1. An electroosmosis pump adapted to be mounted in an electric power generation apparatus having a fuel cell, the electroosmosis pump comprising:
 a housing having a hollow portion; 
 an electroosmotic member accommodated in the housing to partition the hollow portion into an introducing side and a discharge side; 
 a space formed in the housing peripheral to the electroosmotic member; and 
 an elastic piece which separates the hollow portion and the space from each other such that the hollow portion and the space do not communicate with each other, and which supports the electroosmotic member. 
 
     
     
       2. The electroosmosis pump according to  claim 1 , further comprising a cushioning filled in a gap between a wall of the hollow portion and an edge of the electroosmotic member. 
     
     
       3. The electroosmosis pump according to  claim 1 , wherein the electroosmosis pump comprises a plurality of the elastic pieces and a plurality of the spaces, and wherein the plurality of elastic pieces and the plurality of spaces are arranged around the electroosmotic member. 
     
     
       4. The electroosmosis pump according to  claim 1 , further comprising a projection provided on the elastic piece so as to project toward the hollow portion, wherein the electroosmotic member is supported by the projection and the elastic piece. 
     
     
       5. An electric power generation apparatus having the electroosmosis pump according to  claim 1  mounted therein, wherein the electroosmosis pump sends fuel to the electric power generation apparatus, and the electric power generation apparatus generates electricity with the sent fuel. 
     
     
       6. An electronic equipment having the electric power generation apparatus according to  claim 5 , the electronic equipment comprising:
 an electronic equipment body which operates using the electricity generated by the electric power generation apparatus.
